This custom made glass cooling stem uses the DynaVap tip and cap and replaces the standard DynaVap midsection body for increased distance in the vapor path. And being all glass, there is no imparted flavor. It's 12cm long but stretched out would be over 30cm long. This increased distance cools the vapor drastically compared to the stock set up.
It's mesmerizing to see the Serpent's venom coil through the glass!
DynaVap tip and cap sold separately.
